head is also an ancient and justified UNIX command. Its syntax is typically

head -10 wazoo
head -n 10 wazoo
head -c 1024 wazoo
head -1k wazoo

The first two examples print the first 10 lines in the wazoo file. The third and the fourth print the first kilobyte in the file.
Notice that head, like most UNIX utilities, knows nothing about the content and structure of your file.
This example refers to GNUhead, although the first example probably works with any implementation.

A song by The Molly Bloom from the CD "TEMPORAREALITY". Lyrics by David Z. Moss and C. Casey. Note: I am personally acquainted with the authors of this song, and I have obtained their permission to post the lyrics here. (Time permitting, I will add analysis as well at a later date.)

I am driving in my car radio on feeling free
Lines in the road mean nothing to me
I don't cross absent authority
Lines in the road spell authority
I don't cross them because I'm awake

I'm talking to you and you're talking to me
But I want to know what you mean
I look at you and you look at me
But we only see the way that we seemTime passes, love turns to pain
But it's always today in my brain
It's all in, In my head, In my head, It's all in my head

In my car I am driving, driving at something and not arriving
Lines in the road spell reality, I'm as objective as I can be

It's all in, In my head, In my head, It's all in my head
It's all in, In my head, In my head, It's all in my head

Sometimes I remember that it's all in my mind
Radio signals and warning signs
Sometimes I forget the outside world is doing things to me

The Monkees movie. Directed by Bob Rafelson, written by Rafelson and Jack Nicholson, who would go on to make the Oscar-nominated Five Easy Pieces together. If you think you can skip this film because you've sat through countless episodes of the TV show, think again. This is a psychedelic masterpiece on par with Fellini or Buñuel, with more to say than most Beatles flicks, sung in a language mainstream American film no longer knows. It will challenge and confound you. It will make you laugh. And it rocks.

I don't want to give away more of this film's magnificent surprises than I have to, but I'll entice you with a few details: The opening chase sequence reimagines A Hard Day's Night as recurring nightmare, and throws in blissful suicide and mermaids for good measure. The eye in the mirror haunts Davy. Micky gets in the tank and blows up the Coke machine. And the fourth wall is broken over and over and over until you can't tell if any walls are still standing. You'll never forget this one, folks.

The presence or absence of a head was much used formerly as a character in classification. Thus Latreille divided animals into the headless, and those provided with a head; and these again formed two groups, the Vertebral animals, with heads properly so called, and Cephalidia, with small, indistinct, heads. But this classification would separate the oyster and all other lamellibranchmollusks from the snail, cuttlefish, etc.; it is, in fact, an artificial character. The mouth and principal nervous organs are the guides to the anterior end of the body, where the head, when recognizable, is situated.

The head of the vertebrated animals presents a regular series of increasing complexity from the lancelet upward. In that fish the most anterior part of the nervous cord is lodged in a canal scarcely distinct from the rest of it. Ascending in the series, it becomes evident that as the anterior nervous mass enlarges, and the ganglia increase in complexity, the anterior vertebrae change their character; as the brain becomes specialized so does the brain case or skull. In man the brain attains its highest development and the head its greatest complexity, the difference between skull and face being now most pronounced. The increasingly globular form of skull in the vertebrates is due to the greater increase of the cerebral hemispheres relatively to that of the base of the brain and axis of the skull; hence the brain comes in man to overhang the face. See SKULL.

The bottom part of the head typically contains recessed areas that forms the topmost parts of the combustion chambers. The bottom-most parts of the valves are seen here. Usually the spark plugs bolt through the top of the head and the electrodes extend through into this recessed area. The head is then bolted to the engine block (containing the piston and cylinders). The regions formed between the recessed area on the bottom of the head and the block become the combustion chambers, where the magic happens. The interface between the block and the head is typically machined to a very high precision so that a near-perfect seal is created.

Human beings have been messing about in boats for millenia, and until very recently the answer to a call of nature at sea was to lean over the side, pull down one's pants, and let loose. There are several hazards in this action, most of which we won't go into here, but chief among them is the danger that a rogue wave might come along and then it's man overboard. The loss of a crewmember makes it harder to get work done, something that irritates the officers.

The answer to this on a larger ship was to extend a board with several rear-end-sized holes out over the water. This board was usually located at the front ("head") of the ship. Although the aforementioned waves would serve as a natural flushing mechanism (in addition to an occasional nasty icy surprise), the real reason for the board's location was to prevent the offending material from falling through portholes at the rear of the ship into the officers' cabins.

The natural names a Jack might use for this device among his shipmates would probably have been frowned upon in mixed company, and so, visiting the "head" became his primary euphemism.

Today, "head" refers to any marine toilet, or the small cabin that encloses the plumbing fixtures. Be sure to close the petcocks before running her hard, or you might wind up on the bottom!
